The Schneider Electric EZC250H4160 is a 4-pole EasyPact EZC250H moulded-case circuit breaker rated 160 A at 40 °C, with a thermal-magnetic TM-D trip unit. It delivers 85 kA Icu at 220–240 V AC and 10 kA Icu at 550 V AC, meeting the IEC 60947-2 standard for distribution and isolation duty.
At 380–415 V AC the rating drops to 36 kA Icu, still adequate for most panelboard main breakers. The 10 kA Icu at 550 V AC is the limiting case for 480 V systems; verify coordination with the upstream device.
Fixed backplate mounting, front connections both top and bottom. The 35 mm connection pitch matches standard busbar systems. Depth of 60 mm and width of 140 mm fit a typical distribution panel footprint; leave clearance for the toggle handle and positive-contact indication flag.
